Orthopedic Assessment of the Cervical Spine
Importance of the Cervical Spine
- Critical segment in the spinal column.
- Understanding patient history is vital for diagnosing pathologies.
Key Points in Patient History
- Activities Affecting Symptoms: Identify activities or prolonged postures that increase symptoms.
- Pain Location: C1-C4 vertebrae related pain wouldn't impact extremities.
- Sensory Symptoms: Paresthesia, tingling, anesthesia - assess if unilateral (nerve root) or bilateral (spinal cord/meninges).
- Sleep Disturbances: Grade 2 and 3 tissue damage might cause sleep issues.
- Age Considerations: Degeneration common after age 45, nearly universal after 65.
- Mechanism of Injury: Distinguish between chronic and acute injuries.
Pain and Pathology
- Pain with Movement: Indicates mechanical pathology; repetitive movement points to specific flexion/extension issues.
- Chemical Pain: Persistent across movements, indicating different pathology.
- Previous Injuries: Strong predictor of future issues.
- Pain Source: Localized pain suggests muscle/ligament/facet joint involvement, whereas radiating pain suggests nerve root/spinal cord issues.
Ergonomics and Posture
- Importance of assessing ergonomic posture, particularly for sedentary individuals.
- Common issues such as cervical tension headaches linked to sustained neck posture.
Differential Diagnosis
- Unyielding Pain: Possible disc rupture or serious conditions like tumors.
- Symptoms Beyond Cervical Spine: Persistent dizziness or tinnitus suggests non-orthopedic issues.
- Ligament Trauma Indicators: Fearful movement, muscle spasms, focal pain.
Radiculopathy vs. Myelopathy
- Radiculopathy: Unilateral symptoms from nerve root compression.
- Myelopathy: Bilateral symptoms indicating spinal cord involvement.
Common Cervical Spine Disorders
- Spondylosis: Degenerative changes in zygapophysial/facet joints, common in aged individuals.
- Herniated Discs: Common in C4-5 and C6-7, often due to repetitive flexion.
- Stenosis: Narrowing of spinal canal, often age-related, leading to bilateral symptoms.
- Whiplash: Results from sudden extension/flexion, potentially injuring muscles, ligaments, or causing herniation.
Acute Cervical Spine Injuries
- Axial Load Injuries: Most catastrophic; importance of ruling out fracture/dislocation before special tests.
- Mechanism of Injury: Axial load with flexion/rotation most likely to cause severe injury.
- Signs of Serious Injury: Bilateral deficits, odd postural responses indicate possible spinal cord damage.
Special Considerations
- Transient Quadriplegia: Temporary loss of function post-impact; needs spine boarding and imaging.
- Spear Tackler's Spine: Result of improper tackling techniques causing axial loading.
- Muscle Strains and Whiplash: Common from acute impacts, involve muscle, joint capsule, or ligaments.
Bracho Plexus Neuropraxia (Stingers)
- Causes: Stretching, compression, or direct trauma to brachial plexus.
- Common in Sports: Especially football; transient symptoms with a high recurrence rate.
Assessment and Management
- Assessment Tools: Includes bracho plexus stretch test, Spurling’s test, imaging if fracture suspected.
- Management Strategies: Vary from rest and supportive gear to potential surgical interventions in severe cases.
- Return to Play Criteria: Full strength, no symptoms, full ROM required.
Clinical Prediction Rules for X-Ray
- Guidelines for when to pursue imaging based on age, mechanism of injury, symptoms, and neck mobility.
